several smaller branchlets bearing rather closely 

 appressed, sharp-pointed leaves. It is, for ex- 

 ample, hardly to be distinguished from figures 

 of this species given by Velenovsky 40 from the 

 Cretaceous of Bohemia. I also find in the old 

 United States National Museum collections a 

 single specimen, recorded under No. 865, which 

 was collected at Coal Creek by George Hadden. 

 It was not figured by Lesquereux and repre- 

 sents the impression of a fragment from a large 

 branch. It is indistinguishable from figure 23 

 of Plate VII in Lesquereux's "Tertiary flora." 41 



Among the specimens collected by Arthur 

 Lakes at Mount Carbon, Morrison, Colo., from 

 the sandstone near the coal seam, are a number 

 of rather poorly preserved but evidently large 

 branches of a conifer that I am unable to distin- 

 guish from this species. By taking an impres- 

 sion in clay the original form of the branches is 

 restored in a fairly satisfactory manner. The 

 leaves are seen to be rather long, sharp 

 pointed, and spreading, but with incurved tips. 



The small collection made on Crow Creek, 

 Colo., contains three rather poorly preserved 

 specimens of conifers that appear to be refer- 

 able to this species. They are long, ' slender 

 twigs covered with short, appressed scalelike 

 leaves and apparently additional more slender 

 leaves. They are not well enough preserved 

 to warrant a positive reference to this or any 

 other species. 



Occurrence: Laramie formation, Coal Creek, 

 Boulder County, Colo., collected by N. L. 

 Britton about 1884; Mount Carbon, Morrison 

 Colo., collected by A. Lakes in IS 90; Crow 

 Creek about 25 miles northeast of Greeley, 

 Colo., collected by F. H. Knowlton and T. W. 

 Stanton, 1896. The last is questionable.

There appears to be some confusion regarding 

 Lesquereux's Sequoia longifolia. So far as can 

 be made out, Lesquereux had specimens of a 

 long-leaved conifer from Black Buttes, Wyo., 

 to which it is inferred he gave the manuscript 

 name "Sequoia longifolia." Before this species 

 was published, however, specimens thought to 

 represent the same species were obtained from 

 Point of Rocks, Wyo., and the name was first 

 published in the Hayden Annual Report for 

 1874 (1876), page 298, under the designation 

 "Sequoia longifolia Lesq., MSS." In explana- 

 tion he adds: "This species was already de- 

 scribed from Black Buttes specimens." I can 

 not find that it was ever published in connec- 

 tion with the Black Buttes specimens, and it 

 seems that when Lesquereux actually came to 

 publishing a report on the Black Buttes mate- 

 rial he changed the name of the long-leaved 

 conifer common at that place to Sequoia acumi- 

 nata. 42 It is certain that he nowhere definitely 

 recorded Sequoia longifolia as coming from 

 Black Buttes, nor has it since been found there. 



If the above interpretation is correct, as it is 

 believed to be, it establishes Point of Rocks, 

 Wyo., as the type locality for Sequoia longi- 

 folia and excludes the species from Black 

 Buttes. The type specimens are the originals 

 of figures 28 and 29 of Plate LXI of the "Ter- 

 tiary flora" and are Nos. 73 and 74, respec- 

 tively, of the United States National Museum 

 collections. This leaves the specimen figured 

 under this name in Plate VII, figures 14, 14a, 

 of the "Tertiary flora" still to be accounted for. 

 It is said 43 to have come from the " Haley coal 

 mine, 10 miles northeast of Greeley, Colo. 

 (A. C. Peale)"; it. is No. 61 of the United 

 States National Museum collections. I was 

 informed by Dr. Peale that this statement was 

 in error, as he did not collect it and was never 

 at this locality. Inasmuch as Lesquereux 

 pointed out certain marked differences between 

 the Point of Rocks and Greeley specimens and 

 added, "It may be, therefore, that these speci- 

 mens represent two different species," and in 

 further consideration of the uncertainty regard- 

 ing the so-called Greeley specimen, it is appar- 

 ently justifiable to consider only the Point of
